CITY DUST. CAUSE AND EFFECT. 1904. This paper was aimed 



to bring out the relationship between infected dust and the size and number 

 of patent medicine ads. in newspapers, how the number and size of these 

 depend on the amount of infected dust in the community. Such ads are 

 indicators. In the light of later observations, the list of "dust ads" should 

 be enlarged to include other ads. notably health food ads and ads relating 

 to teeth and skin, similarly tobacco ads. 



Tobacco along with alcohol must be considered a sedative. Both give 

 ease. The Chinese get ease through opium; the East Indian through 

 hasheesh. People the world over use certain drugs for ills that accompany 

 life under unsanitary house and town conditions. They are pseudo remedies. 

 The proper remedy is to clean up. This can not be over-emphasized. 



Did time permit here should come a review of tobacco ads. how they can 

 be classified. It is interesting to study these. Some are sensible, they are 

 worth studying; on the other hand some are downright drivel, evidently 

 written by old men in their dotage. Which are "the best" tobaccos, cigars 

 and cigarettes? Men who must use tobacco find less need for smoking or 

 chewing constantly if strong brands are used. I could tell how men who used 

 two-for-a-quarter cigars and smoked constantly changed to "tufers" and 

 smoked less, and at a greatly reduced cost. 



I could tell of men who "came back," men who had lost health, perhaps 

 not so much by the use of tobacco itself as through the infected air they 

 inhaled while using it. I have in mind men whom I advised to get ease by 

 the use of good air rather than attempt to get ease through tobacco. In 

 other words, offset bad air by good air and reduce the reaction and thus 

 reduce ills. (Tables to show how this works out were given in my paper on 

 The Alcohol Problem, last year.)
